Abstract (en)
[origin: US2019284488A1] Methods and apparatus for recovering power in a hydroprocessing process are described. The method involves the use of a power-recovery turbine in place of, or in addition to, a control valve. A hydrocarbon feed stream is combined with a portion of a hydrogen stream. The combined stream is heated, and the heated stream is introduced into a hydroprocessing reaction zone having at least two beds. The heated stream is contacted with a first hydroprocessing catalyst to form a first hydroprocessed stream. At least part of a portion of the hydrogen stream is combined with the first hydroprocessed stream to form a first quenched hydroprocessed stream. The first quenched hydroprocessed stream is contacted with a second hydroprocessing catalyst to form a second hydroprocessed stream. At least a portion of the second portion of the hydrogen stream is directed through a power-recovery turbine to generate electric power.
